Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It conveys a read-only operation ('Get') and specifies the authenticated bot as the subject, making side effects and auth context clear. It does not detail response fields or potential errors, but for a simple self-profile endpoint, this is adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
